In the body (1), there is located through radial hole (5). In the bottom part (3), having a shape truncated cone, which is closed to the body (1) there is located the fixed channel tool (6) and it is located in the axial direction.

Description

Technical field

The present invention relates to a dental instrument holder used manually in dental medicine, which comprises a body provided with a transverse opening for inserting means to prevent the instrument from falling into the patient's interior as a lung or stomach.

BACKGROUND OF THE INVENTION

To prevent the duct instrument from falling or dropping into the patient, detent devices have been provided that are fastened to the instrument and form a hinge whose other end is fixed firmly on the thumb or hand of the attendant so that it can release the instrument , which holds, for example, between the thumb and forefinger without the risk of the tool falling into the patient. These catching devices are retained on the tool holder either through a through hole and / or an annular groove with a latch system.

Up until now was unknown holder that ^- would allow the capture of the two mentioned devices. The main drawbacks of the prior art holders are that their convex shape forces the holder to hold the holder very firmly, since it tends to eject outside the hand of the attendant due to its shape. The cylindrical shapes of the holders do not allow good positioning of the care worker's fingers on the holder. It is also known to have a hollow form of the holder which adversely affects, by its hollow shape, the crumbling of the nursing rubber gloves, making their use difficult.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to overcome these disadvantages and to provide a tool holder that is versatile and very functional.

The object of the present invention is to provide a channel tool holder used manually in dentistry, which is provided with means to prevent these instruments from falling into the patient, which consists of a double-conical body on which an annular groove is arranged. provided in a plane perpendicular to the longitudinal axis of the body, a radial bore is provided in the body and a channel tool is fixed in the axial direction in the lower frustoconical part of the body.

According to a preferred embodiment, the upper frustoconical portion and the lower frustoconical portion of the two-conical body are connected to each other by smaller bases.

Further features and advantages will be apparent from the description of an exemplary embodiment.

Overview of the figures in the drawing

The invention is explained in more detail below by way of example with reference to the accompanying drawings, and the invention is of course not limited to this example, where:

FIG. 1 shows a side view of the holder according to the invention, and FIG. 2 is a cross-sectional view of the holder in the plane of the radial bore along line A-A of FIG. First

DETAILED DESCRIPTION OF THE INVENTION

The channel tool holder body 1 consists essentially of a lower frustoconical portion 2 and an upper frustoconical portion 3, each preferably having a frusto-conical shape. An annular groove 4 is formed at the junction of both of these frustoconical portions 2, 3. In at least one of the frustoconical portions 2, 3 a radial opening 5 is provided, the cross-section of which is evident from the section in FIG. 2 is formed essentially by two frustoconical sections 5a, 5b which are connected to each other by their smaller bases. Such an expanded structure, which essentially forms a funnel, facilitates the insertion of the tab of the catch.

In a possible variant, it is assumed that the radial opening 5 is arranged at the level of the annular groove 4.

In contrast, it can be provided that at least one radial bore 5 and one annular groove 4 do not intersect, as shown in FIG. First

In the drawing, a two-cone-shaped holder body 1 is described, but it goes without saying that the invention also includes an arrangement in which the holder body 1, or more precisely its cross-section, can shrink from circumference to center whether symmetrically or not.

The two frustoconical parts 2, 3 of the holder body 1 are preferably provided with longitudinal circumferential teeth 7, which are regularly distributed on their outer surface.

In the exemplary embodiment, the frustoconical portions 2, 3 have an apex angle and a value of 8 ° to 9 °.

According to conventional practice, the holders are formed of molded plastics at the end of the blade of the channel tool 6, fixedly fixed at the lower end of the body 1 in the axial direction.
